The Easy Way

"The easy way, right!?" I search her face for answers.

"Of course, Luke. Please bend over the table and spread your legs, I will need to perform another test." I'm uncertain, but I feel willing to obey her.

She places a hand on my back and comes up behind me. "Many years ago when scientists experimented on the differences between males, females, and futas, they found that when either sex came in contact with futanari ejaculate it mutated the cells to accentuate the dominant chromosome's traits, the X chromosome."

With very little fanfare, I felt June's tongue prod my asshole. "Woah," I shout as I go to turn and face her, but she holds up a finger and I pause. She rims me and prods my hole a few times and then addresses me. It felt good, but was weird.

"Bear with me, Luke. Females grew bigger boobs, wider hips, and gained an increased libido. Males... Males saw your condition: a leaky cock, a shrinking penis, and growing female traits when exposed to increased quantities until by all measures they were genetically women. During this transition process, it seemed that the only thing that could stimulate the penis was the g-spot."

My asshole was tingling now and puckering for attention. She took her finger and stuck it inside me and then I felt something, my cock rose for the first time in many hours. Once one finger fit snugly, she pushed in a second, and then a third. Each opened me up and brought my cock to a higher angle.

"Much like the transexual XXY fluids could arouse, transform, and sedate males, the ejaculate of female origin could preserve the male traits and return their bodies to a functional equilibrium." She paused and stood back up, keeping her fingers inside me. "You are hard, are you not?"

"Yes, my cock feels fucking amazing!" I exclaim.

"That's because I am stimulating your prostate with my entire hand up your ass." I turn back in surprise to see her arm disappear inside me... But it feels so good.

"So I need to get a girl to cum on my cock. Sounds easy. You want to help?" I say with a glint in my eye as I grab hold of my aching cock and picture fucking June until her tongue hangs out.

June pulls her hand out my asshole and I hear her unzip and remove her pants. She wants to fuck. "That is correct, Lukie, but that is not the easy way. This is..." Before I can turn my head to see her, I feel another warm object prod at my gaping asshole. As I behold June's naked form, her giant, round tits and hair that reaches down to her waist, I witness the biggest cock I have ever seen leaking precum onto my asshole... And strangely enough, I want it.
